MEMBER FCR SHOE-UPPERS.

Application iled October 20, 1917. Serial No. 197,611.

. To all whomit may concern:

Be it known that I, WILLIAM F. LAUTEN- SCHLAGER, a citizen of the UnitedStates, and

residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented .v

a new and useful Member for Shoe-Uppers,

of which the following specification is a fulll disclosure.

My invention relatesv to a member for Aa shoe upper, or similar article,where two sheets are to be held together for unitary manipulations, in amanner permittingsome degree of relative movements of thesheets, as inthe folded margin of a shoe upper.

The object of the invention is to produce a sheet article, such as ashoe upper part, comprising superposed shoe parts, such as the marginsof a shoe upper, adheslvely united to an intermediate member, such as afolded tape, enabling the superposed parts to be manipulated as aunitary member, while providing slight relative movement between thesuperposed members.

` The features of the invention will be more fully set forth in thedescription of the accompanying drawings, forming a .part of thisspecification, wherein:

'Figure 1 is a perspective view, partly in section, showing a lastedshoe upper.

showing my method of edge folding.

Fig. 3 is an enlarged perspective section, showing the skived portionofthe marginal edges.

Fig. 4 is an enlarged perspective section of the folded adhesive tapeused in my method.

Fig. 5 isy an lenlargedperspective section on line ff-V5, Fig. 2. 1',

Fig. 6 isan enlarged perspective section on line 6-6, 2. y

. Fig. 7 is an enlarged perspective section on line 7-7, Fig. 1; v

The finish edges of shoe uppers, generally, terminate in skived edgesand such edges are ordinarily folded inwardly and secured by cement.This cementing operation is eX- pensive and slow and is frequentlyineffective for retaining the edge in folded condition during thesubsequent stitching operation.

The method I preferably `employ for producing my new article consists intaking a strip of tape folded upon itself to constitute the insert l,only-the exterior surfaces having adhesive application, much cheaperthan cement. skived portion 2 with free` edges 3 coincident to the lineof fold and the folded tape edge 4 pointing inwardly. The skived portionof the upper is bent over this insert, as indicated in Fig. 5, bothinner surfaces ofthe` upper margin being adhesively' secured to andretained by the adhesive surfaces of the folded tape, the normal line'offinishing stitches being shown by dotted lines 5, Fig. 5. This'ins'ertand folding operation can either be done by hand or machinery, and, ifthe latter, the tape folding and inserting can be run along cordinatelywith the ma?v chinery for folding over the upper margin'.

This constitutes a satisfactory, temporary securance, the process ismuch cheaper and cleaner than the cementing treatment and the finishedproduct is better because the margin is advantageously reinforced bythis folded tape insert. 1

The member so made is primarily inan upper, tip, or vamp, or to longcurves, and is not intended particularly for relatively vsharp curves.As, for instance, vthe same method and structure may be employed for thevamp edge 6 and tip edge 7, and the saving of labor are material items.

The outer surfaces of thel folded tape when moistened adhere to theinner-.folded surfaces of the upper and so constitute a This insert isplaced along the tended for application to straight edges of- 1 marginalreinforcement of value in preventing the stitches from pulling out, andalso produces a superior finished appearance as well as a more durableshoe. ,v

The fiat character of the folded tape insert, provides a reinforcedmargin `into which theneedle of the stitching machine will readily take,drawing the stitch through two thicknesses of the upper, vamp ort'ip,and the two wings of the folded tape, forming a stout stitch anchorage.The tape may be wide enough to project below the folded over upperedge,'or it may terminate flush with this vdown 'turned upper edge.Preferably a wide tape is employed inthe folded top edge 8 of the shoeupper. This wide tape extends approximately twice the width of the fold(see Fig. 6), and when the lining 9 is assembled with the upper, the eX-posed portion l() of the adhesive tape surface is moistened, serving asan anchorage gina1edge lfolded over,

Fig. 7), and as a reinforcement for the top of the inished shoe. Y

Having described my invention, I claim z- 1. A shoe upper member havinga marand a vfolded tape having adhesive exterior surfaces secured withinthe shoe material' fold, the folded edge of the tape being outermost.

2. A shoe upper member havin'g a marginal edge folded over, and a foldedtape having adhesive exterior surfaces, lying within the folded margin,the folded edge ofl the tape coinciding with the turned over edge of thematerial, of the tape coinciding with the fold of the material. y i

3. A shoe upper member having a margin folded upon itself, andl anadhesive tape placed within the fold to aline a medial free portion ofthe tape with the turned edge of the upper member. f

and the double edges 2l. sheet article of the nature disclosed, having.a base member and securing them together and' placed to aline a medialfree portion of said member with the edge of the member overlying thebase member.

5. -A sheet article of the nature disclosed, comprising superposedmembers, and a flexible intermediate adhesive member uniting thesuperposed members and having a medial free portion permitting slightrelative movement between the superposed members.

In witness whereof I hereunto subscribe my name, as`attested by the twosubscribing witnesses.
